CENTER-TAPPED TRANSFORMER - A center-tapped transformer includes tubular first and second spools, a primary winding unit, and first and second secondary winding units. The first spool has a first surrounding wall, a first pin-mounting wall, and a first pin set mounted on the first pin-mounting wall. The second spool has a second surrounding wall, a second pin-mounting wall, and a second pin set mounted on the second pin-mounting wall. The second surrounding wall has an inner diameter larger than an outer diameter of the first surrounding wall. The primary winding unit is wound on one of the first and second surrounding walls. The first and second secondary winding units are wound on the other one of the first and second surrounding walls.

CENTER-TAPPED TRANSFORMER - A center-tapped transformer includes a spool, a first primary winding unit, and first and second secondary winding units. The spool has a surrounding wall defining a spool axis, and a partition plate unit extending in radial outward directions from the surrounding wall so as to divide the spool into axially extending first and second spool parts. The partition plate unit cooperates with the surrounding wall to define at least one notch. The first primary winding unit surrounds the first spool part and passes through the notch to surround the second spool part. The first and second secondary winding units are disposed on one side of the first primary winding unit and surround the first and second spool parts, respectively.

DUPLEX AUTOMATIC DOCUMENT FEEDER AND DUPLEX DOCUMENT SCANNING METHOD USING THE SAME - A duplex automatic document feeder includes first, second, third, and fourth paths, an ejecting path, a scanning module, first and second reversing roller units, a feeding tray, and an ejecting tray. A document is moved from the feeding tray to the scanning module for scanning of a first side surface thereof. Subsequently, the document is moved along a second-side scanning path defined by the first reversing roller unit, the third path, a portion of the first path, the fourth path, and the first reversing roller unit to allow for scanning of a second side surface thereof. After the first and second side surfaces are scanned, the document is moved along a document-inverting path defined by the second reversing roller unit, a portion of the fourth path, the ejecting path, a portion of the second path, the first reversing roller unit, and the ejecting tray.

CONTROL DEVICE FOR USE IN A RESONANT DIRECT CURRENT/DIRECT CURRENT CONVERTER - A control device for controlling a switch unit of a resonant direct current/direct current converter includes a frequency modulation controller and a pulse selector. The frequency modulation controller is adapted to be coupled electrically to the converter for receiving a correcting threshold value and output information of the converter, and for generating a synchronization signal according to the correcting threshold value and the output information received thereby. The pulse selector is adapted to be coupled electrically to the converter and the frequency modulation controller for receiving the correcting threshold value, the output information and the synchronization signal, and for generating a driving signal according to the correcting threshold value, the output information and the synchronization signal received thereby. The driving signal is adapted to drive the switch unit and has a working period. The driving signal switches between high and low signal levels at a frequency that is substantially equal to that of the synchronization signal during the working period.

EFFICIENT CHIEN SEARCH METHOD IN REED-SOLOMON DECODING, AND MACHINE-READABLE RECORDING MEDIUM INCLUDING INSTRUCTIONS FOR EXECUTING THE METHOD - An efficient Chien search method in Reed-Solomon decoding is adapted to be implemented in a processor having a parallel processing instruction set. The method includes the following steps: (a) calculating an error evaluation value; (b) subjecting the error evaluation value to mapping processing so as to find an index adjusting value; (c) storing a symbol index into an error location memory corresponding to a location index; (d) updating the location index according to the index adjusting value; (e) updating the symbol index; and (f) repeating steps (a) to (e) a particular number of times. The method primarily aims to reduce program flow branching so as to enhance the computation efficiency of the Chien search process.

Earplug Earphone - An earplug earphone with a special engagement is provided. The earplug earphone includes a body and an earplug. The body has a protruding connecting portion, wherein the protruding connecting portion has a first engaging element on the inner side thereof. The earplug includes a protruding portion having a second engaging element. The earplug is fixed to the body by engagement of the engaging elements. After the protruding connecting portion is combined with the protruding portion, a buffering segment spaced apart in an appropriate distance is formed between the earplug and the body. The buffering segment has an advantage for the earplug to match different external auricles of different users and to be inserted in the ears of different users, thereby making the earplug earphone of the present invention further conform to ergonomics.
